Hi, 
I'm trying to paginate my score nicely and the automatic paging isn't good enough. So I'm doing all the page breaks manually -- and a certain situation is causing an assertion failure on compilation:

MIDI output to `BeiMannernScore.mid'...

Fitting music on 9 or 10 pages...

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.

Assertion failed!

The problem occurs with the page break on a specific bar. For now I've done the obvious thing and gone with a working state -- it's not critical.

Happy to push the code up to a Gist for anyone that wishes to debug the issue. Let me know.

(This is apparently not happening if I build on Linux, only in Windows).

I'll confirm that your example from down-thread does not give an exception error under 64-bit linux. I see that you are using a self-built binary; have you tried downloading and installing a binary from the website, to isolate possible issues with your local environment?

Cheers,
Colin
